Maximum increase in cardiac output during pregnancy is seen in: (AIPG 2010)

B 36 weeks

C During labour
D Just after delivery

Ans. D

Just after delivery

1. The cardiac output starts to increase from 5th wk of pregnancy and reaches its peak (40-50%) at about 30-34 wks.

2. Thereafter it remains static till labour (+ 50%) and immediately following delivery (+ 70%) over the pre-labour values.

3. This increase in cardiac output is due to squeezing out of blood from the uterus into the maternal circulation (auto transfusion) during labour and in the immediate post-partum.

4. Cardiac output returns to the pre labour values by 1hr following delivery and to the pre pregnant levels by 4 weeks’ time.
